98f7203680 - Teach Expr::isConstantExpr() about InitListExpr's (and offsetof, since I noticed it was missing). 
- Rename CheckInitializer() to CheckInitializerTypes().
- Removed the isStatic argument to CheckInitializerTypes() and all of it's subroutines. Checking for constant expressions is now done separately.
- Added CheckForConstantInitializer().

e6b0ec8b5e Fix Sema::ActOnDeclarator() to call MergeFunctionDecl for function decls that aren't in scope. Since C functions are in a flat namespace, we need to give them special treatment (when compared with variables and typedefs).

Fix Sema::MergeFunctionDecl to allow for function type compatibility (by using the predicate on ASTContext). Function types don't have to be identical to be compatible...

1b0ea82459 Substituted all instances of the string "Objc" for "ObjC". This fixes 
some naming inconsistencies in the names of classes pertaining to Objective-C
support in clang.

9bad62c72a Merge all the 'assignment' diagnostic code into one routine, decloning 
it from several places.  This merges the diagnostics, making them more
uniform and fewer in number. This also simplifies and cleans up the code.

Some highlights:
1. This removes a bunch of very-similar diagnostics.
2. This renames AssignmentCheckResult -> AssignConvertType
3. This merges PointerFromInt + IntFromPointer which were always treated the same.
4. This updates a bunch of test cases that have minor changes to the produced diagnostics.

1daa3cfbae TargetInfo no longer includes a reference to SourceManager. 
Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation.
Added many utility methods to FullSourceLoc to provide shorthand for:

    FullLoc.getManager().someMethod(FullLoc.getLocation());
    
instead we have:

    FullLoc.someMethod();
    
Modified TextDiagnostics (and related classes) to use this short-hand.

f727faf2ed Explicitly set the string literal type from "char *" to "constant array of char". 
At this point, I am fairly certain the front-end is correct. Unfortunately, the back-end is still unhappy.

That said, I've commented out the two lines in globalinit.c that are causing problems.

Chris, please have a look...thanks!

2c20c38ced Have Sema::CheckConstantInitList skip semantic analysis when the element type is a record (until we implement the FIXME). This removes a bogus error for the following code...

#define NUMHELICOPTERRECTS 5

static NSRect helicopterRects[NUMHELICOPTERRECTS] = {
    {{27, 0}, {18, 11}},	// Bottom
    {{0, 8}, {4, 11}},		// Tail
    {{0, 16}, {50, 1}},

205ec3d07a Yesterday, I simplified how we stream top-level decls. 
After a discussion with Ted, we both came to the conclusion that adding a "HandleTopLevelDeclaration" hook to ASConsumer is far more elegant. The default implementation of HandleTopLevelDeclaration will be responsible for iterating over the ScopedDecl (which has a chain of the decls:-).

TODO: Once Ted adds HandleTopLevelDeclaration, make sure TagDecls are chainged appropriately...

197616c3a8 Several fixes/simplifications surrounding how we stream top-level decl AST's. 
The following code...

typedef struct cssm_data {} CSSM_DATA, *CSSM_DATA_PTR;

struct Y { int A; };

struct X { int A; } D; 

struct X E, F;

...now produces the following output...

> ../../Debug/bin/clang xx.c -ast-print
Read top-level tag decl: 'cssm_data'
typedef struct cssm_data CSSM_DATA;
typedef struct cssm_data *CSSM_DATA_PTR;
Read top-level tag decl: 'Y'
Read top-level tag decl: 'X'
Read top-level variable decl: 'D'
Read top-level variable decl: 'E'
Read top-level variable decl: 'F'

...which is much more accurate than the previous -ast-print output...

typedef struct cssm_data CSSM_DATA;
typedef struct cssm_data CSSM_DATA;
Read top-level variable decl: 'D'
Read top-level variable decl: 'E'
Read top-level variable decl: 'E'

1a6bb70ad0 Set loc earlier in CheckSingleInitializer to avoid emitting a 
diagnostic without a location.  This produces:

simpleTest.c:2:18: error: initializer element is not constant
int *myPointer = &(myArray[2]);
                 ^~~~~~~~~~~~~

instead of:

ff4dbff4f4 Remove Action::ObjcActOnMethodDefinition(). Rationale: 
- It is not an "action" - it is never called by the parser.
- It was only used by one method, Sema::ObjcActOnStartOfMethodDef().

As a result, the logic it embodied is now directly implemented in Sema::ObjcActOnStartOfMethodDef().
